Title: Improvements relating to landing gear of aircraft
IPC: B64C25/14
Filed: 1938-11-09
Abstract: 521,161. Aircraft landing-gear. DOWTY, G. H. Nov. 9, 1938, No. 32575. [Class 4] An aircraft landing-gear comprising a pillar with a wheel-carrying lever pivoted to its lower end has a shock absorber acting on the lever which is at least partly enshrouded by a hollow portion of the lower extremity of the pillar. Where the wheel is steerable or has a castor action, means are provided for centring the wheel when the load is removed or upon actuation of retracting gear. Fig. 1 shows a tail wheel mounted in a fork 6 pivoted to an offset bracket 4 on a pillar 3 swivelling in a sleeve 28. A shock absorber 9 is pin-jointed at 10, 11 to a bracket 8 on the fork 6 and to the sleeve 3. The sleeve 28 is pivoted to the aircraft frame at 31 and carries a lever 27 to which a bell crank lever 25 is pivoted. One arm of this lever is connected to a jack 29 and the other to a link 24 which is connected by a pin 23 to a sleeve 19 carrying a locking pin 20 for engaging an eye 21 on the aircraft frame. The sleeve 19 carries a cam 18 which cooperates with a cam 16 on the pillar 3 to centre the wheel as the pin 20 is withdrawn. The pin 20 is withdrawn by the link 24 upon initial movement of the jack which simultaneously disengages the pin 23 from a notch in an arcuate guide 33 on the frame, further movement of the jack turning the sleeve about the pivot 31. For a front steering wheel the axis of the pillar 3 is inclined forwardly and is arranged to pass through the wheel axle when normally loaded. The wheel is detachable by removing blocks 13. Fig. 3 shows a modification in which the fork 6 is connected to a piston 39 in a shock absorber cylinder 42 by a link 37 having a ball end 38. The piston forces oil through restricted passages in a partition 40 against air pressure. A centring cam 36 is pinned through slots 46 in the link 37 to a block 44 acted upon by a spring 47 so that under no load the cam 36 is resiliently held against a co-operating cam 35 on a fixed sleeve 42.

When the vehicle tilts excessively, the mass 11 moves to one side and breaks the circuit. The switch can be operated by hand by means of a plunger 23 passing through the casing and operated through linkage 22, 29.

The shut-off valve 22 of a prepayment gas meter with spaced inlet and outlet is within a gas-tight valve box 18 located inside the meter casing proper and immediately below the inlet 14 or outlet 16, one side of the valve communicating with the inlet or outlet, and the other side with a conduit 20 or chamber communicating with the distributing valve or valves of the meter. In the meters described, a gas-tight partition 8 separates an upper region 4 from a lower region 6 containing the measuring chambers. The valve box 18 is located between outlet 16 and region 6, as shown, or inlet 14 and region 4. The prepayment mechanism 12 may be on the side of the meter adjacent box 18, so that the valve operating spindle passes through a single stuffing box 28, or on the opposite side, the spindle passing through one stuffing box in the meter wall and one in the valve box wall. The valve box and prepayment mechanism may alternatively be secured to the front wall or top of the meter casing.

Title: Improvements in or connected with apparatus for conveying metal sheets in rolling mills
IPC: B21B39/02
Filed: 1922-11-30
Abstract: 211,263. Price, C. E. Nov. 30, 1922. Rolling.-Rolled metal sheets are conveyed between the passes of a mill by means of a conveyer comprising lower belts 4, 5 and an upper belt 6 arranged as shown in Fig. 4, the sheets being held between the taut upper runs of the lower belts and the slack lower run of the upper belt. The belt pulleys are mounted on shafts having bearings in rectangular frames 14, 15 provided with base members 18 and anchored to vertically adjustable cross bars 21 in the roll housings 3 by means of hook bolts 20. Further adjustment of the frame member is obtained by bolts 22 bearing against the roll housing and passing through frame extensions 23. The pulley shaft 10 is driven from a power shaft 16, the upper belt being driven from the shaft 12 through gearing 17. The speed of the belts is preferably slightly greater than that of the initial pair of rolls in order to prevent overlapping of the sheets. In a modification, the two lower belts may be replaced by a single broad belt. The sheets are guided to and from the conveyer by inclined guides 26 and side guide-plates. A clutch is provided to stop the conveyer if the sheets are incorrectly positioned.

The intermediates may be co-condensed with hydroxylated silanes or siloxanes in the presence of a suitable catalyst, e.g. n-hexylamine, as described in Specification 874,559, and can be used in one-component room temperature curing rubbers and resins when mixed with condensation catalysts, such mixtures being stable when kept moisture-free, but gel and cure when exposed to atmospheric moisture.  Condensation catalysts specified are certain amines, phosphoric and carboxylic acid salts of basic amino compounds, carboxylic acid salts of quarternary ammonium hydroxides and of any metal ranging from Pb to Mn in the electromotive series of metals, and the aminoalkylsiloxanes and -silanes disclosed respectively in Specifications 684,296 and 716,536.  Numerous examples of catalysts are given.  Pigments, heat stability additives, fillers, perfumes and plasticizers may be added. In a typical example (1) a hydroxy-terminated dimethylpolysiloxane, toluene, pyridine (as HCl acceptor) and SiCl4 were mixed together in that order with stirring; 2-methoxy-ethanol was added thereto after 15 mins., and after a further 15 mins. the pyridine hydrochloride was removed and the solvent stripped off leaving a polymer of the formula <F\1> This polymer was mixed with an end-blocked dimethylpolysiloxane (as plasticizer), silica aerogel and di-n-hexylamine and poured into a film in air to form a tough rubber mass.
